Embodiment 1

[0042] Embodiment 1 A kind of summer spinach planting method

[0043] 1. Variety selection

[0044] The temperature is high in summer, and spinach planting needs to choose varieties that are relatively heat-resistant, bolt-resistant, fast-growing, and high-yield; Jingbo No. 6 is selected as the cultivated variety.

[0045] 2. Selection of plots

[0046] Select plots in the summer fallow period for off-season cultivation of spinach.

[0047] 3. Build a shed

[0048] To build a shed, there is a vertical air vent on the shed roof with a width of 30cm; the plastic film at the front of the shed is raised to a height of 1m.

[0049] Dig a drainage ditch at a distance of 1m from the front of the greenhouse, with a width of 50cm and a depth of 50cm to avoid water accumulation. While doing a good job of ventilation in rainy days, fasten the shed tightly to prevent rainwater from flowing into the shed and causing rotten roots and dead seedlings. Irrigation uses a combination of spr...

Abstract

The invention provides a method for planting spinach in summer and a special light-dispersing cooling and thermal radiation protective screen for the method. The method for planting spinach in summer includes the steps of greenhouse building, protective screen covering and continuous cropping obstacle prevention. According to the method, a greenhouse arch frame is covered with the protective screen, light intensity in a spinach planting greenhouse is 48 klux, and the shading rate is 50-60%. Greenhouse building includes the steps that the greenhouse is built, a longitudinal ventilation port is formed in the top of the greenhouse, and a plastic film at the front end of the greenhouse is uplifted by 1 m. Continuous cropping obstacle prevention includes the steps that soil is turned up and irrigated with ozone water with the mass concentration being 70%, the soil is sealed for one week, and air exhaust is conducted. By means of the method, the quality of summer spinach is obviously improved, the yield of the summer spinach is obviously increased, the disease and insect pest occurrence rate of the summer spinach is lowered, and the low-temperature environment and proper light can be provided for growth of the summer spinach.

Description

technical field [0001] The invention relates to a summer spinach planting method and a special astigmatism cooling thermal radiation protection net, belonging to the field of agricultural technology. Background technique [0002] Spinach (Spinacia oleracea L.) is a cultivated species in the genus Spinacia of Chenopodiaceae, an annual or biennial herb native to the southern temperate zone. It is an important vegetable crop, rich in VE, VC and minerals Fe, Zn, etc. "King" is widely planted in the north and south of our country, and it is also the main vegetable crop generally consumed by the people of our country. Spinach is a cold-resistant vegetable, which is the strongest cold-resistant vegetable among green leafy vegetables, but it is not resistant to high temperature, it is difficult to germinate under high temperature, and the rate of dead seedlings is high. When the temperature is higher than 25°C, the growth is hindered, the yield is low, the quality is poor, and even...
